IMPROVEMENT IN WINE AND CIDERPPRESSES.

ThevScheule referred to in these' LetrersrPatent and making part of thesame.

' Toallwhomit may concern Be it known that I, THOMAS W. Gnrslnn, ofRiusy selville, county of Logan and State of Kentucky, have invented anew and useful Improvement in Zine and Ciderflress; Aand I do herebydeclare that the following isa full, clear, and exact descriptionthereof, reference being had to the annexed drawing making .a partofthis specification.

--The nature of my invention relates to that class of wine andcider-presses in which the grapes or apples are placed in a perforatedvessel and the juice pressed therefrom by means of a screw or othermechanical power,

My improvement has for its object the saving of time and anincreased-yield 0i' wine or cider, and consists in placing a springofany suitablenature and capacity under the foto'f the screw;

In construct-ion my invention is substantially as follows:

A A are two upright posts supporting the cast-iron beam B and thewoodencross-timber C.

' The drawing represents a vertical cross-section taken througlrthecenter of Athe screw.

I) is the curb.

E, the.pomace.-

At F is seen thebed of -the press, and

G, an elevated bed, on which the curb D rests.

H is the screw, and Y I, the ordinary cast-iron fo'ot, held in place bythe set-screw i. n

My improvement consists in placing on the disk 'J the cap K, with aprojection, k, on the bottounand placedlin the center therein.

.A rubber spring, L, its over the projection 1.', but does not entirelyiill the cap K.

In operation my improvement isI as follows:

vWhen the curb is first filled with pomace and moved under the press thecap is not used, as but little pressure is required to bring the pomacedown turned back so as to give room for the introduction ofthe cap K,with the rubber spring L, under thel foot I.

The screw is then again brought down as far as the operator hasstrength, with a lever which compresses the rubber almost to itsgreatest capacity'. v

. 'Ihe operator may then proceed to grind apples, and the spring1 L willcontinue the pressure, giving ,the pomaee time to settle until the forceof the spring has been expended. l

It is found in practicethat to overcome the-capillary attractionexisting between the fluid and pomace is such as to require a certainamount of time to separate them, or, in other words, the operationmustbe slow.

Now, in order to accumulate the force exerted by Athe operator on thescrew, and to have this force continued after the screw has been left, Iplace a spring of any suitable construction or material, such as rubber,steel, brass, dto., between the `end of the screw and the poinace, ormay be attached between the nut on a screw-press and the cross-beam, orunder the bed of the press, as may seein best to serve the pur'- posehere intended; or a scroll-spring, such as used in clocks, may bewoumlaround the screw or other parts communicating witlrit, so as' tocause a continuous downward pressure of the screw by the reaction oi'the spring. v

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is v The combina-tion, in a wine andcider-press, of the springs L with serew H andA screw-plate I',substantially as shown, for the purpose set forth.
